RFID Zapper

Hardware

All we need for RFID zapper is old camera (with flash) or flash itself, since it's less complex than coilgun and needs less power than real EMP (which would destroy all our electronics or bring legal problems, so we should not try to build it in city)

There were also some ideas with magnetrons from microwave owens, but i am not sure how securely we can control emission of such radiation and we should not try this until we will really know what we are doing since my (eye)balls do not want to be fried.
